When we look at a flashlight, there are many different factors that can decide a flashlights runtime. Let’s take a look at how some of these factors affect it…
-- Brightness. A flashlights runtime is generally measured when it is on the highest brightness mode, so you can increase the runtime by using a lower brightness setting.
-- Ambient Temperature. If you’re going to be using your torch in extremely hot or extremely cold temperatures make sure you know that the performance of your batteries will change.
-- Type of Battery. Some batteries are more effective than others and will change the runtime of your flashlight quite dramatically. The better quality the batteries are and the larger they are the longer they will power the flashlight.
Whether you’re busy camping or simply using your flashlight when the power goes out, the last thing you want is a dim, flickering light. Make sure you steer clear of these unfortunate situations and remember runtime when you buy a flashlight.
